Under kVAR Generated Inhibit Time
Under kVAR Generated Inhibit Time (Parameter 394) allows you to inhibit an
under power factor leading trip and warning from occurring during the motor
starting sequence. It is adjustable from 0…250 seconds.
Table 327 - Under kVAR Generated Inhibit Time (Parameter 394)
Over kVAR Generated Inhibit Time
Over kVAR Generated Inhibit Time (Parameter 398) allows you to inhibit an
over reactive power (kVAR) generated trip and warning from occurring during
the motor starting sequence. It is adjustable from 0…250 seconds.
Table 328 - Over kVAR Generated Inhibit Time (Parameter 398)
Under kVAR Consumed Trip
The E300 relay trips with an Under kVAR Consumed indication if:
• No trip currently exists
• Under kVAR Consumed Trip is enabled
• Current is present
• Voltage is present
• Under kVAR Consumed Inhibit Time has expired
• The total reactive power (kVAR) consumed is less than the Under kVAR
Con
su
med Trip Level for a time period greater than the Under kVAR
Consumed Trip Delay.
If the E300 relay trips on an under reactive power (kVAR) consumed, the:
• TRIP/WARN LED status indicator flashes a red 2-long / 3-short blink
